Using the free body diagram above for a 1-kg box being pushed across a level floor, describe the change in motion for the box when the applied force is 10N and the frictional force is 8 N.
A)
The box will decelerate at a rate of 8 m/s?
B)
The box will accelerate at a rate of 8 m/s2
The box will decelerate at a rate of 2 m/s?
D
The box will accelerate at a rate of 2 m/s?

Which diagram correctly demonstrates the various forces acting on a ball moving horizontally with some speed?

Estimate the change in the gibbs energy and molar gibbs energy of 1.0dm3 of octane when the pressure acting on it is increased from 1.0 atm to 100 atm. the mass density of octane is 0.703 g cm−3

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?
